Technical Information Shore A Hardness ~28 (after 28 days) (ISO 868) Secant Tensile Modulus ~0.45 N/mm2 at 100 % elongation (+23 °C) (ISO 8339) Movement Capability ± 25 % (ISO 9047) Elastic Recovery ~90 % (ISO 7389) Tear Propagation Resistance ~7.0 N/mm (ISO 34) Service Temperature −40 °C to +70 °C Resistance to Weathering 8 (ISO / DIS 19862) Joint Design The joint width must be a minimum of 6 mm and a maximum of 50 mm. A width to depth ratio of 2:1 must be maintained. Joint widths less than 10 mm are generally for interior connection joints or crack control joints and therefore considered as non-movement joints. Example of typical joint widths for joints between concrete elements for exterior applications if the joint sealant is classified as ±25 % movement capability according to ISO 9047, calculation according to DIN 18540: Min. joint width [mm] Min. joint depth [mm] Example of typical joint widths for joints between concrete elements for exterior applications if the joint sealant is classified as ±35 % movement capability according to ASTM C 719, Calculation according to ASTM C 1472-10: Min. joint width [mm] Min. joint depth [mm] All joints must be correctly designed and dimensioned in accordance with the relevant standards and codes of practice before their construction. The basis for calculation of the necessary joint widths are: | ||||||||||||||||||||||||||||||||||||||||||||||||||||
